Oh the size!

I hope this question isn't too bothersome/inappropriate but I'm pretty much horrible with animated icons and everything I tried just ended up with the complete disfiguration of the original piece.

So I've recently come across this gem by lazy_princess but sadly the size of it (over 100 KB) won't allow me to use it here. So could anyone resize this for me and/or tell me how that can be done without losing too much of its quality?

I use PS 7 & Image Ready and Animake.

Thanks in advance!
